Damage to the DNA of microorganisms from decay of incorporated I and the relationship of DNA damage to lethal effects
Iodine-125 decays by electron capture and is known to cause severe molecular damage to small organic molecules via vacancy cascades. In an examination of the biological effects of this decay mode we have labelled coliphages T1 and T4, as well as E. coli, with I-5-iododeoxyuridine, which is incorporated into DNA in place of thymidine. Labelled organisms are generally stored in liquid nitrogen at -196C during decay and are periodically assayed for loss of viability and for breakage of DNA, using neutral and alkaline sucrose gradient sedimentation techniques. Briefly, our experiments have demonstrated drastic damage to DNA from the decay of incorporated I, as would be predicted from the data for small molecules. (auth
